Graphs are tools which help to illustrate data and make the information more understandable to the audience. There are many different types of graphs, i.e. pie graphs, bar graphs, line graphs just to name a few, and each is utilized for a different purpose. In creating a graph, the person must decide which type will best illustrate the information that they need to convey (Graphs). They also must choose the parameters and categories by which the graph will be labeled and explained to the person looking at it. For most graphs, the ultimate purpose is relation, showing how one piece of information is related to or changes with the inclusion of another piece of information.
Bar Graphs
As its name suggests, a bar graph is made up of a series of bars which represent different categories of information. By lining the bars against one another, the information that they contain is directly compared (Department). Bar graphs are constructed by defining items...
It also shows a relationship between two pieces of information. First, information that is related to the label on the x-axis is found and then data related to the y is identified and the data incorporated into the graph (Graphs). However, rather than a bar, a dot is placed at the point where the x and y data meet. After all the data points have been recorded, a line is drawn connecting the dots so that a pattern can be discerned.
Pie Chart
Pie charts are unique graphs in that they are firstly circular in shape. Secondly, pie charts are used only to display information as it relates to a whole. The totality of data percentages, 100%, represents the entirety of the circle (Department). The circle is then broken down…

Investigate Distributions with GraphsPart 11. Explain the difference between a categorical variable and a quantitative variableThe difference between a categorical variable and a quantitative variable is that the latter is one that fluctuates and changes in amount whereas a categorical variable is one that changes in kind. Basically, variables that are categorical have dissimilar values or categories and there is no distinctive ordering to these categories along a primary measurement.

As such, we may state that the exchange rate remained significantly stable over the period of time we have been analyzing so far. On the other hand, it is much simpler to explain this decreasing exchange rate from an investment point-of-view. The American companies have found India to be one of the best resources of human potentials in the world. At incredibly low wages, ranging from 2-300 dollars to less
Diabetes as Presented Online From Two Different Websites Diabetes is a common condition which is a form of affliction that pervasive in the U.S. Diabetes is a condition where a person's blood glucose levels are higher than normal as a result of the fact that the pancreas is unable to make enough insulin or can't use insulin as well as it should -- thus, causing insulin to be built up in
Electrocardiogram Currently there are different types of tests to study the behavior of the heart and monitor it. These tests are extremely important, because let us know in time if the heart is failing or has a problem. And because of that, today we submit to treatment or surgery to correct them when they are still small and manageable, before our life is at risk. The electrocardiogram, ECG or EKG, is
